Referring to FIG. 1 and FIG. 2 , an embodiment of the presentapplication provides an electronic vaporization device 100. Theelectronic vaporization device 100 includes a vaporizer 10, and thevaporizer 10 can be configured to heat and vaporize aerosol generationsubstrates such as flowers and leaves, herbs or pastes.

The vaporizer 10 includes a first housing 11 and an electrode holder 12,and the electrode holder 12 is provided with an electrode. Referring toFIG. 3 and FIG. 4 , the vaporizer 10 further includes a matchingstructure, and the matching structure includes a first matching portion131 and a second matching portion 132. The first matching portion 131 isarranged on one of the first housing 11 and the electrode holder 12, andthe second matching portion 132 is arranged on the other of the firsthousing 11 and the electrode holder 12. That is, the first matchingportion 131 and the second matching portion 132 are neithersimultaneously arranged on the housing 11, nor simultaneously arrangedon the electrode holder 12. Specifically, when the first matchingportion 131 is arranged on the housing 11, the second matching portion132 is arranged on the electrode holder 12; and when the first matchingportion 131 is arranged on the electrode holder 12, the second matchingportion 132 is arranged on the housing 11. The first matching portion131 is matched with the second matching portion 132 in an anti-rotationmanner in a circumferential direction of the vaporizer 10. That is, thefirst matching portion 131 is matched with the second matching portion132 to limit mutual rotation between the electrode holder 12 and thefirst housing 11 in the circumferential direction of the vaporizer 10.

With the foregoing arrangement, relative positions of the electrodeholder 12 and the first housing 11 in the circumferential direction ofthe vaporizer 10 do not change easily. Therefore, a position of theelectrode arranged on the electrode holder 12 does not change easily,the vaporization assembly 15 is kept connected to a power supply 32through the electrode at all times, and positions of other componentsthat are in contact with the electrode holder 12 do not change easily,to ensured that various components in the vaporizer 10 closely matchwith each other, thereby improving the product yield.

Referring to FIG. 5 , in an embodiment, the first housing 11 includes afirst body 111 and a first mounting ring 112, and the first mountingring 112 is arranged in the first body 111. The electrode holder 12includes a base body 121 and a first electrode 122 arranged on the basebody 121 (referring to FIG. 3 ), and at least part of the base body 121is arranged in the first mounting ring 112. One of the first matchingportion 131 and the second matching portion 132 is arranged on the basebody 121, and the other is arranged in the first mounting ring 112. Thatis, the first matching portion 131 and the second matching portion 132are neither simultaneously arranged on the base body 121, norsimultaneously arranged on the first mounting ring 112. Specifically,when the first matching portion 131 is arranged in the first mountingring 112, the second matching portion 132 is arranged on the base body121; and when the first matching portion 131 is arranged on the basebody 121, the second matching portion 132 is arranged in the mountingring 112. The first mounting ring 112 and the base body 121 are bothmade of conductive materials. For example, both the first mounting ring112 and the base body 121 are made of metal materials. In this way, thefirst electrode 122 arranged on the base body 121 may be connected tothe power supply 32 through the base body 121 and the first mountingring 112. It should be understood that, in other embodiments, thearrangement manner of the first housing 11 and the electrode holder 12is not limited to the foregoing manner. For example, the first housing11 may include only the first body 111, and the electrode holder 12 mayinclude only the base body 121.

Specifically, the first body 111 is cylindrical with openings at bothends in an axial direction, and the first mounting ring 112 is annular.Certainly, in other embodiments, specific shapes of the first body 111and the first mounting ring 112 are not limited.

In an embodiment, the first matching portion 131 is a protrusionprotruding from one of the first mounting ring 112 and the base body121. The second matching portion 132 is a groove recessed in the otherof the first mounting ring 112 and the base body 121. The protrusion isembedded in the groove, and the protrusion is embedded in the groove inan anti-rotation manner in the circumferential direction of thevaporizer 10 to restrict rotation of the base body 121 relative to thefirst mounting ring 112. Specifically, the base body 121 is detachablyconnected to the first mounting ring 112, and both the groove and theprotrusion extend in the axial direction of the vaporizer 10. That is,the first matching portion 131 is detachably matched with the secondmatching portion 132 in the axial direction of the vaporizer 10. In thisway, the first matching portion 131 is matched with the second matchingportion 132 to allow the base body 121 and the first mounting ring 112to be separated from each other. That is, in this embodiment, the firstmatching portion 131 is matched with the second matching portion 132 torestrict the rotation of the electrode holder 12 relative to the firsthousing 11. However, the matching of the first matching portion 131 andthe second matching portion 132 does not restrict detachment of theelectrode holder 12 from the first housing 11 in the axial direction. Inaddition, through detachable connection between the base body 121 andthe first mounting ring 112, it is convenient to separately clean theelectrode holder 12 and the first housing 11.

Further, a cross-sectional shape of the protrusion is a zigzag shapearranged in the circumferential direction of the vaporizer 10, and across-sectional shape of the groove matches the cross-sectional shape ofthe protrusion to increase the anti-rotation effect. It is conceivablethat, in other embodiments, specific structures of the first matchingportion 131 and the second matching portion 132 are not limited,provided that the electrode holder 12 can be restricted from rotatingrelative to the first housing 11 while can be detached from the firsthousing 11.

In an embodiment, the first electrode 122 is an annular shape arrangedin the circumferential direction of the vaporizer 10, and the firstelectrode 122 is sleeved outside an end of the base body 121 thatextends into the first mounting ring 112. A first opening 1221(referring to FIG. 3 ) in communication with the outside runs throughthe first electrode 122 in a thickness direction (a radial direction ofthe vaporizer 10), and a second opening 1121 (referring to FIG. 5 ) runsthrough the first mounting ring 112 in the thickness direction. A firstair outlet channel 14 (referring to FIG. 6 ) is provided between thefirst mounting ring 112 and an inner wall of the first body 111. Thefirst air outlet channel 14, the second opening 1121 and the firstopening 1221 are sequentially communicated. In this way, the externalair can flow through the first opening 1221 to the second opening 1121,and flow out from the second opening 1121 to the first air outletchannel 14.

Optionally, in the circumferential direction of the vaporizer 10, awidth of the first opening 1221 is greater than a width of the secondopening 1121. In this way, during mounting of the electrode holder 12,communication between the second opening 1121 and the second opening1121 is ensured without requiring precise alignment in thecircumferential direction, so as to ensure smooth airflow. Certainly, insome other embodiments, the width of the first opening 1221 mayalternatively be equal to or less than the width of the second opening1121, which is not limited herein.

Specifically, a plurality of the first openings 1221 spaced apart fromeach other are arranged in the circumferential direction of thevaporizer 10. The quantity of the second openings 1121 matches thequantity of the first openings 1221 to ensure smooth airflow. Certainly,in some other embodiments, there may also be only one first opening 1221and one second opening 1121. Referring to FIG. 6 , in an embodiment, theelectrode holder 12 further includes a first insulating member 123 and asecond electrode 124. The second electrode 124 extends out of the basebody 121, and the first insulating member 123 is sleeved between thesecond electrode 124 and the base body 121 to block electricalconnection between the first electrode 122 and the second electrode 124.Referring to FIG. 7 , an air inlet channel 1241 and an air outlet 1242are provided in the second electrode 124. The air inlet channel 1241 iscommunicated between the outside atmosphere and the air outlet 1242, andthe air outlet 1242 is in communication with the first opening 1221. Inthis way, the external air flows to the air outlet 1242 through the airinlet channel 1241, and sequentially flows from the air outlet 1242 tothe first opening 1221, the second opening 1121 and the first air outletchannel 14.

A plurality of the air outlets 1242 spaced apart are arranged in thecircumferential direction of the second electrode 124 to ensure smoothairflow.

In an embodiment, the protrusion is arranged on the base body 121. Theelectrode holder 12 further includes a sealing member 125 (referring toFIG. 3 ). An end of the sealing member 125 in the axial direction abutsagainst the first electrode 122, and the other end abuts against boththe protrusion and the first mounting ring 112. In addition, the sealingmember 125 has an inner surface abutting against the base body 121, andan outer surface abutting against the inner wall of the first mountingring 112 (referring to FIG. 6 ). In this way, the first mounting ring112 can support the electrode holder 12 in the axial direction, toprevent the electrode holder 12 from being separated from the firstmounting ring 112 under the action of gravity. In addition, the sealingmember 125 can prevent air from leaking to the outside from between thebase body 121 and the first mounting ring 112.

Referring to FIG. 6 , the vaporizer 10 further includes a vaporizationassembly 15, and the vaporization assembly 15 is detachably arranged atan end of the first body 111 that is away from the electrode holder 12.In this way, after smoking is completed, only the used vaporizationassembly 15 needs to be detached, and after being cleaned, otherassemblies can be reused with a new vaporization assembly 15, therebyreducing the cost and resources.

Referring to FIG. 8 , the vaporization assembly 15 includes avaporization core 151, a third electrode 152 and a fourth electrode 153.The vaporization core 151 is detachably arranged at an end of the firstbody 111 that is away from the electrode holder 12; the third electrode152 and the fourth electrode 153 are both arranged at an end of thevaporization core 151 that is close to the electrode holder 12; thethird electrode 152 abuts against the second electrode 124, and thefourth electrode 153 abuts against the first electrode 122. In this way,the electrode holder 12 plays the role of supporting and positioning thevaporization assembly 15.

A liquid storage tank is arranged in the vaporization core 151, and asecond air outlet channel 16 (referring to FIG. 6 ) in communicationwith the first air outlet channel 14 is formed between the outer wall ofthe vaporization core 151 and the first housing 11. At least part of theouter surface of the vaporization core 151 forms a vaporization surface154 (referring to FIG. 8 ), and the vaporization surface 154 is incommunication with the second air outlet channel 16. Specifically, thevaporization assembly 15 further includes a heating body. The heatingbody is placed in the vaporization core 151; the third electrode 152 andthe fourth electrode 153 are electrically connected to the heating body;the heating body generates heat to vaporize an aerosol generationsubstrate located in the liquid storage tank, and the aerosol flows fromthe vaporization surface 154 to the second air outlet channel 16 fordischarge.

Specifically, referring to FIG. 9 , the vaporization core 151 includes acylindrical body 1511 and a sealing cover 1512. The sealing cover 1512closes an end of the cylindrical body 1511 that is close to theelectrode holder 12, and defines a liquid storage tank together with thecylindrical body 1511. The third electrode 152 and the fourth electrode153 are arranged on the sealing cover 1512, and a surface of the sealingcover 1512 facing the electrode holder 12 forms the vaporization surface154. The gas generated by vaporization and the external air sequentiallyflow to the outside through the first opening 1221, the second opening1121, the first air outlet channel 14 and the second air outlet channel16.

In an embodiment, the cylindrical body 1511 and the sealing cover 1512are both sintered by ceramic. When the surface of the sealing cover 1512facing the electrode holder 12 forms the vaporization surface 154, theouter surface of the cylindrical body 1511 is made into a dense layer ora glaze layer. It should be understood that, both the outer surface atan end of the cylindrical body 1511 that is close to the sealing cover1512 and the outer surface of the sealing cover 1512 can serve as thevaporization surface 154. In this case, the outer surface at an end ofthe cylindrical body 1511 that is away from the sealing cover 1512 maybe made into a dense layer or a glaze layer. In other embodiments, thecylindrical body 1511 may alternatively be made of a liquid-impermeablematerial, and the sealing cover 1512 may be made of porous ceramics. Thecylindrical body 1511 and the sealing cover 1512 are jointly sintered,which is not limited herein.

Referring to FIG. 8 , the third electrode 152 is dot-shaped, and thefourth electrode 153 is arranged surrounding the third electrode 152.Specifically, the fourth electrode 153 is annular. In this way, theelectrical connection effect can be ensured without requiring thealignment between the second electrode 124 and the third electrode 152or the alignment between the first electrode 122 and the fourthelectrode 153.

Further, the first electrode 122 includes at least two contact portions1222 that are in contact with the fourth electrode 153 (referring toFIG. 3 ). That is, in the specific embodiment, an end of the firstelectrode 122 that is close to the fourth electrode 153 has a gap thatis in communication with the first opening 1221. In this way, the firstelectrode 122 is divided into at least two contact portions 1222 spacedapart by the first opening 1221. Certainly, in some other embodiments,the arrangement manner of the first electrode 122 is not limitedthereto.

An end of the cylindrical body 1511 that is away from the sealing cover1512 is provided with a liquid storage port in communication with theliquid storage tank. The vaporization assembly 15 further includes avaporization plug 155, the vaporization plug 155 is partially plugged inthe liquid storage port, and an exhaust channel 156 (referring to FIG. 9) communicated between the second air outlet channel 16 and the outsideis provided on a portion of the vaporization plug 155 protruding fromthe liquid storage port. In this way, the vaporization plug 155 can notonly close the liquid storage port, but also serve as a channel for theair to flow out of the vaporizer 10.

Further, referring to FIG. 1 and FIG. 2 , the electronic vaporizationdevice 100 further includes a suction nozzle 20. The suction nozzle 20is mounted at an end of the first body 111 that is away from theelectrode holder 12, the vaporization assembly 15 is located between theelectrode holder 12 and the suction nozzle 20, and the suction nozzle 20is in communication with the exhaust channel 156. In this way, when theuser sucks through the suction nozzle 20, the air sequentially entersthe suction nozzle 20 through the air inlet channel 1241, the firstopening 1221, the second opening 1121, the first air outlet channel 14,the second air outlet channel 16 and the exhaust channel 156 for theuser to suck.

The second housing 31 includes a second body311 and a second mounting ring 312. The power supply 32 and the secondmounting ring 312 are both arranged in the second body 311. An end ofthe base body 121 of the electrode holder 12 facing the second mountingring 312 is provided with a thread-connected portion 1211, and thethread-connected portion 1211 is in threaded connection with the secondmounting ring 312. Specifically, the second mounting ring 312 is made ofa conductive material, and the base body 121 is connected to the powersupply 32 through the second mounting ring 312. The power supplyassembly 30 further includes a second insulating member 33 and aconductive member 34.

The conductive member 34 is connected to thesecond electrode 124.

Another embodiment of the present application further provides thevaporizer 10 included in the electronic vaporization device 100. In thevaporizer 10, the electrode holder 12 is matched with the first housing11 through the first matching portion 131 and the second matchingportion 132, and relative positions of the electrode holder 12 and thefirst housing 11 in the circumferential direction of the vaporizer 132do not change easily. A position of the electrode arranged on theelectrode holder 12 does not change easily, the vaporization assembly 15is kept connected to a power supply 32 through the electrode at alltimes, and positions of other components that are in contact with theelectrode holder 12 do not change easily, to ensure that variouscomponents in the vaporizer 10 closely match with each other, therebyimproving the product yield.

The vaporizer 10 and the electronic vaporization device 100 provided inthis embodiment have the following beneficial effects:

1. The first matching portion 131 is matched with the second matchingportion 132 to limit the mutual rotation between the electrode holder 12and the first housing 11 in the circumferential direction of thevaporizer 10, and relative positions of the electrode holder 12 and thefirst housing 11 in the circumferential direction of the vaporizer 10 donot change easily.

2. Both the protrusion as the first matching portion 131 and the grooveas the second matching portion 132 extend in the axial direction of thevaporizer 10, so that the electrode holder 12 can be easily detachedfrom the first housing 11 in the axial direction.

3. A width of the first opening 1221 is greater than a width of thesecond opening 1121.
